First we need to divide this number by 4
4250/4= 1,062.50
This amount is equal to 1/4 so you and your younger sibling will receive that much.
The older sibling will receive 2/4 of the amount (the remainder) so we need to double this amount.
1062.5x2= 2125
so your older sibling will receive 2125 pesos and you and your younger sibling will receive 1062.50 pesos.
